Abstract
A battery pack includes a first battery module, the first battery module including unit batteries, a first plate, and a second plate, and a second battery module, the second battery module including unit batteries, a first plate, and a second plate. The first battery module may be stacked on the second battery module, the second plate of the first battery module may be between the first battery module and the second battery module, and the second plate of the first battery module may support the unit batteries of the first battery module and contact the first plate of the second battery module.
Claims16
A battery pack, comprising:
- a first battery module, the first battery module including unit batteries, a first plate, and a second plate having a channel shape that includes side parts extending from a top part, the unit batteries of the first battery module being between the first and second plates of the first battery module;
- a second battery module, the second battery module including unit batteries, a first plate including gas inlets, and a second plate, the unit batteries of the second battery module including respective vents and being between the first and second plates of the second battery module, each of the respective vents being aligned with one of the gas inlets;
- and
- a sealing member disposed between the side parts of the second plate of the first battery module and the first plate of the second battery module, the sealing member sealing the side parts of the second plate of the first battery module to the first plate of the second battery module to form a duct open to the second plate of the first battery module and the first plate of the second battery module, wherein:
- the first battery module is stacked on the second battery module such that each of the vents of the unit batteries of the second battery module faces the first battery module thereabove in a vertical direction,
- the second plate of the first battery module is between the first battery module and the second battery module, and
- the second plate of the first battery module supports the unit batteries of the first battery module and contacts the first plate of the second battery module, the second plate of the first battery module and the first plate of the second battery module extending along the unit batteries of the second battery module and being combined to form the duct, the duct being coupled to the respective vents of the unit batteries of the second battery module so as to receive gases vented from the unit batteries of the second battery module.

A method of forming a battery pack, the method comprising:
- providing a first battery module, the first battery module including unit batteries, a first plate, and a second plate having a channel shape that includes side parts extending from a top part, the unit batteries of the first battery module being between the first and second plates of the first battery module;
- arranging a second battery module adjacent to the first battery module such that the first battery module is stacked on the second battery module, the second battery module including unit batteries, a first plate including gas inlets, and a second plate, the unit batteries of the second battery module including respective vents and being between the first and second plates of the second battery module, each of the respective vents being aligned with one of the gas inlets;
- and
- sealing the side parts of the second plate of the first battery module to the first plate of the second battery module with a sealing member disposed between the side parts of the second plate of the first battery module and the first plate of the second battery module to form a duct open to the second plate of the first battery module and the first plate of the second battery module, wherein:
- the first battery module is stacked on the second battery module such that each of the vents of the unit batteries of the second battery module faces the first battery module thereabove in a vertical direction,
- the second plate of the first battery module is disposed between the first battery module and the second battery module,
- the second plate of the first battery module is disposed to support the unit batteries of the first battery module and to contact the first plate of the second battery module,
- the second plate of the first battery module and the first plate of the second battery module extend along the unit batteries of the second battery module and are combined to form the duct, and
- the duct is coupled to the respective vents of the unit batteries of the second battery module so as to receive gases vented from the unit batteries of the second battery module.
